A long exposure of Earth from the I.S.S by Don Pettit of NASA [x-post /r/pics] (i.imgur.com)

This is the thing about reposts - I have never seen this before, so to me, it's fucking awesome.
[–]halasjackson 5 points6 points7 points 21 days ago
What are the white specks?
[–]SIVILIZATIOUS[S] 4 points5 points6 points 21 days ago
They are super cells that are enriched with lightning. Again, there are so many of them, because it is a very long exposure.
[–]sonar_un 2 points3 points4 points 21 days ago
Looks like lightning to me.

Yeah this is new to me and it is awesome.

Each star is a different color. Is that from processing or is that actually how it looks up there in space? Is the color of the starlight dependent on distance and/or age ie. the more distant stars are red-shifted?
[–]OrangeredStilton 1 point2 points3 points 21 days ago
Dependent on age and size, roughly. Thus the talk you'll hear of red giants, blue stars, etc.
Nothing in this galaxy is far enough away to redshift due to Hubble expansion, nor moving fast enough to redshift by plain velocity, so it's all about the temperature.

They also look like that on Earth with a long enough exposure. Human night vision is almost completely monochromatic, so with naked eye most stars just look white. There are notable exceptions, for instance Betelgeuse (a red giant) is markedly reddish.

it makes me think of super high speed internet
